## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability arbipulse-gpu-compute-price-arbitrage-5f508963
```

Example prompt: What's the current $/GPU-hour spread for H100s across vast.ai and RunPod versus AWS on-demand, and how much would I save running one GPU around the clock for a month on the cheapest marketplace option?

## When to prefer this

Use this endpoint when an AI agent needs to make cost-optimal decisions about GPU provisioning for training or inference workloads — specifically when comparing marketplace clouds (vast.ai, RunPod) against AWS on-demand for a known GPU class. Prefer this over generic cloud pricing APIs when you need a pre-computed spread multiple and savings estimate rather than raw price lists.

## Known failure modes

- Upstream provider API unavailable — stale or missing price for one or more providers
- Invalid GPU class specified — returns error if GPU model not in supported enum
- Network timeout to live provider APIs — partial results or error response
- GPU class temporarily unavailable on a given marketplace — missing slot in response

## How this service works

GPU compute price arbitrage — ONE $0.25 call returns live $/GPU-hour for one GPU class (H100, H200, B200, A100, L40S, RTX 4090/5090) across the vast.ai marketplace floor, RunPod community/secure cloud, and the AWS on-demand anchor, plus the spread multiple and 24/7 monthly savings versus the anchor. Marketplace-vs-hyperscaler spreads of 3-4x are routine in 2026 — for agents provisioning training or inference this is direct spend recovery. Live provider APIs, no LLM in the path.

## Output

Returns live $/GPU-hour pricing for the requested GPU class from vast.ai marketplace floor, RunPod community and secure cloud, and AWS on-demand anchor; includes the spread multiple (e.g. 3.2x cheaper than AWS) and estimated 24/7 monthly dollar savings versus the hyperscaler anchor price
